Editorial note
Maybe silanes, dissolved in liquid ammonia, could work at low temperatures, but i doubt it my thought with the undersea vents is that, if there was a diverse hadean or archean ecosystem of non-carbon-based life, some of it should have survived in the parts of the vents that are too hot for carbon-based life. maybe the cells that froze to death in boiling water would become food for carbon-based extremophiles, but the cells in the hotter parts of the rock should be safe but we don't observe that, and i think that the most likely explanation is that there wasn't any silicone-based life in the hadean nucleic acids are definitely not a requirement for all forms of life
